Specification of Letters Patent.

Patented Nov. 28, 1911..

To all whom it may concern:

Be it known that l, Lnwis JAMEs lEtossI- Tnn, a subject of the King of Great Britain and Ireland, residing at 2 "Wilson street, Redfern, near Sydney, in the State of New South Wales, Commonwealth of Australia, have invented certain new and useful Tmprovements in Tobacco-Pipes, of which the following is a specification.

The purpose of this invention is to provide a tobacco pipe which will cool the smoke by extending the distance traveled by it before reaching the mouthpiece, which will reduce to a minimum the amount of nicotin reaching the mouth of the smoker and to accomplish these desirable results in asimple and inexpensive manner.

The essential features of my invention consist in the peculiar construction of the pipe stem and core piece as hereinafter more fully described.

In order that my invention may be clearly understood I shall now refer to the accompanying drawings in which Figure 1 is a sectional view of my improved pipe. Fig. 2 is a perspective view of the core piece detached. Fig. 3 is a double stemmed pipe according to my invention.

Like numerals of reference indicate c0rresponding parts in each figure.

Referring to the drawings :.The smoke from the bowl travels down passage 15 and enters the annular passage 35, passing along the passage 36 into the chamber 21, thence through the central hole 37 and radial passage 38 into the first of the annular circumferential grooves 39, 39 formed on the core 40 from which it passes into the next groove by the passage 41 cut in the division wall and so on through the series, the passages 41, 41, being formed alternately on diametricallyr opposite sides of the core, thus insuring a long travel of the smoke, which eventually passes into the passage 2t in the mouthpiece 25.

In the double stemmed pipe shown in Fig.

3, the end groove in the upper stem communicates with the passage 28 through which the smoke enters the lower stem and travels the series of grooves formed on the lower core to the chamber 30 whence it onters the central hole 42 communicating with the passage 24 in the mouthpiece 25.

When it is desired to clean the pipe, it is only necessary to draw out the core pieces (one of which is attached to the mouth piece of the pipe and the other to the plug 33) and to cleanse them by Wiping or byany other convenient method. The hollow stem in Fig. l is closed at its outer end by a plug 20 and in the double stemmed pipe shown in Fig. 3 the hollow stems are closed by plugs 20, 33, and 34:. These hollow stems can be cleansed by removing the plugs and passing a piece of any absorbent fabric therethrough or by washing out the parts.

ll am aware that annularly grooved core pieces for insertion within the stems of tobacco pipes are not in themselves novel and l do not claim such broadly, but only in so far as pointed out in the claim for novelty following this description.

What I claim as my invention is Tn a tobacco pipe, the combination with the stem having a longitudinal cylindrical passage therethrough, of a core piece snugly fitting in said passage and circumferentially grooved to form a plurality of flanges integral with a central rod, each of said flanges being provided with a slot from its outer edge d1ametrically opposite to the corresponding slot in the adjacent flange, said slots forming a zig-zag passage for the smoke and said central rod forming battles in said zig-zag passage, and a mouthpiece substantially as described.

Signed at Sydney, New South Wales, this 10th day of May, 1910.

LETS JAMES ROSSITER.
